Motherboard |
The main printed circuit board in an
electronic device, particularly a computer, which may contain sockets that
accept additional boards |

CPU |
The part of a computer which controls
all the other parts. Designs vary widely but, in general, the CPU consists
of the control unit, the arithmetic and logic unit (ALU) and memory
(registers, cache, RAM and ROM) as well as various temporary buffers and
other logic. |

RAM |
A data storage device for which the
order of access to different locations does not affect the speed of
access. This is in contrast to, say, a magnetic disk, magnetic tape or a
mercury delay line where it is very much quicker to access data
sequentially because accessing a non-sequential location requires physical
movement of the storage medium rather than just electronic switching. |

Video Card or AGP |
A circuit board fitted to a computer,
especially an IBM PC, containing the necessary video memory and other
electronics to provide a bitmap display. |

Optical Drive #1 CD-ROM |
A non-volatile optical data storage
medium using the same physical format as audio compact discs, readable by
a computer with a CD-ROM drive. |

Optical Drive #2 DVD |
An optical storage medium with
improved capacity and bandwidth compared with the Compact Disc. DVD, like
CD, was initially marketed for entertainment and later for computer users. |

3.5" Floppy Drive |
A peripheral device that reads and
writes hard disks or floppy disks. The drive contains a motor to rotate
the disk at a constant rate and one or more read/write heads which are
positioned over the desired track by a servo mechanism. It also contains
the electronics to amplify the signals from the heads to normal digital
logic levels and vice versa. |

A hardware device consisting of a
number of mechanical buttons (keys) which the user presses to input
characters to a computer. |

NIC |
A body that provides information,
assistance and services to network users. These will typically include
telephone and electronic mail "help desk" type services for
users and network information services such as hostnames and addresses
which are accessed automatically by computers using some client-server
protocol |

Modem |
An electronic device for converting
between serial data (typically EIA-232) from a computer and an audio
signal suitable for transmission over telephone lines. In one scheme the
audio signal is composed of silence (no data) or one of two frequencies
representing 0 and 1. |

Sound Card |
A plug-in optional circuit card for
an IBM PC. It provides high-quality stereo sound output under program
control. A "multimedia" PC usually includes a sound card. One of
the best known is the Sound Blaster. |

Monitor |
A cathode-ray tube and associated
electronics connected to a computer's video output. A monitor may be
either monochrome (black and white) or color (RGB). Color monitors may
show either digital color (each of the red, green and blue signals may be
either on or off, giving eight possible colors: black, white, red, green,
blue, cyan, magenta and yellow) or analog color (red, green and blue
signals are continuously variable allowing any combination to be
displayed). Digital monitors are sometimes known as TTL because the
voltages on the red, green and blue inputs are compatible with TTL logic
chips. |
